FIM2010: How to Use OOB Function Evaluator workflow to parse EMail for MailNickname

Issue: Scenario is that we want to create a workflow in the portal to populate the 'MailNickname' attribute from the EMail attribute. For example, if the
email address is Test1@contoso.com, the MailNickname should be Test1.

Solution: Since there is no 'Length' or 'Find' function in the built in function evaluator we have to accomplish it a bit differently. Here we'll assume everyone in the portal has an @contoso.com or @fabrikam.com email address. Note the
length of @contoso.com is 12, and @fabrikam.com is 13 characters.
